Answer :
Final answer:
The left side of the periodic table is mainly occupied by metals, including representative metals, transition metals, and inner transition metals. Metalloids are found along a diagonal interface between metals and nonmetals, with semi-conducting properties.
Explanation:
The elements found on the left side of the periodic table are primarily metals. This includes both the representative metals, which are found in groups 1 and 2 (also known as the alkali metals and alkaline earth metals, respectively), as well as the transition and inner transition metals. The transition metals occupy the central block of the periodic table and are known for their ability to form various oxidation states and compounds. The inner transition metals are composed of the lanthanides and actinides, some of which are radioactive elements. Metals in general are characterized by their ability to conduct heat and electricity, malleability, ductility, and typically a shiny appearance.
Metalloids are located on a diagonal line separating metals and nonmetals, and they display a mixture of properties from both groups, often being semiconductors. Nonmetals, which are found on the right side of the periodic table, are not as dense as metals, generally have lower melting points, and are poor conductors of heat and electricity.
